D-Alanine（Cat No.:R061117）is the D-enantiomer of the naturally occurring amino acid alanine, with the molecular formula C3H7NO2. Unlike L-alanine, which is incorporated into proteins, D-alanine plays a critical role in bacterial cell wall biosynthesis, where it is a component of the peptidoglycan layer. It contributes to structural integrity and resistance to enzymatic degradation by forming D-Ala-D-Ala dipeptide cross-links. D-Alanine is also used in biochemical research, antibiotic studies, and chiral synthesis. It is a white crystalline solid, water-soluble, and serves as a stereospecific building block in pharmaceutical and microbial applications.
